Soda Jungle

Soda Jungle is the jungle-themed fifth world of New Super Mario Bros. U and New Super Luigi U. It is the largest world in the game, both physically and in terms of courses. The world, as its name implies, takes place in a jungle inspired by Giant Land from Super Mario Bros. 3, Forest of Illusion from Super Mario World and World 4 from New Super Mario Bros. in terms of appearance, layout and theme as the jungle is giant-themed within both the world map and the normal levels, as well as big enemies or big variations of small enemies, like Big Goombas and Big Koopa Troopas. The dead trees in the center of the jungle leads to a haunted area, containing a few extra courses, including Boo enemy courses. When the player enters the area, the area pixelates before loading again. The name is derived from soda as a reference to the acid water in the world. There are twelve levels in this world, with the first Airship level appearing before entering the section, five normal levels in the outer areas, two that are in the haunted area along with the second Ghost House and the BooEnemy Courses, a secret level, the Tower level and Castle level. A green Toad House and two red can be found here as well. The boss of this world is Iggy Koopa.

In the haunted area in Soda Jungle, Mario must take an alternate exit in either Painted Swampland or Deepsea Ruins (Painted Pipeworks or Deepsea Stone-Eyes for Luigi in New Super Luigi U) in order to create a pathway that will allow him to leave the haunted area and proceed through the world, in a manner similar to the Forest of Illusion in Super Mario World; taking the normal paths otherwise in either stage will bring him back to the pathway in front of Which-Way Labyrinth (Boo's Favorite Haunt in New Super Luigi U).

This is the only world in the game with more than one section: The haunted forest sub-area, the outside and the inside.

This is also the only world in the game to have an English name actually transliterated from the original Japanese.

Every world before Soda Jungle leads to the latter, either by a world-skipping shortcut or completing the previous world's castle, and, Soda Jungle leads to every world afterward, besides Peach's Castle.

Soda Jungle-1 from both New Super Mario Bros. U and New Super Luigi U is the only stage to include pipe-dwelling Big Piranha Plants, which haven't been seen in a sidescrolling Mario title since Super Mario Bros. 3.
